Claims the priority of US Provisional Patent Application No. 62 / 363,694 by Zhang et al., entitled "Efficient Power Utilization for Enhanced Component Carriers," filed on July 18, 2016.

The following relates generally to wireless communications, and more specifically to efficient power utilization for extended component carriers (eCCs), multicarrier systems, broadband systems, and the like.

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, and broadcasting. These systems may be able to support communication with multiple users by sharing available system resources (eg, time, frequency, and power). Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, and orthogonal frequency division multiple access (OFDMA) systems, ( For example, there is a Long Term Evolution (LTE) system). A wireless multiple access communication system may include several base stations, each of which simultaneously supports communication for multiple communication devices, also known as a user equipment (UE).

A UE operating in a wireless communication system that supports carrier aggregation (for example, communication over two or more frequency carriers) may include, for example, the UE may contain information related to the UE during a particular time interval. Increased power consumption can be incurred, such as when monitoring a set of carriers that may not be included. For example, the UE may monitor system bandwidth, including multiple carriers, for downlink data transmission resources and data transmission permissions. However, some or all carriers in the system bandwidth may not contain permissions or data directed to the UE during a particular time interval. Monitoring all carriers in the system bandwidth (for example, broadband monitoring) can result in unnecessary power consumption.

The techniques described relate to improved methods, systems, devices, or devices that support efficient power utilization for wireless communication systems that use Extended Component Carriers (eCCs). The techniques described herein allow the user equipment (UE) to monitor a portion of the entire system bandwidth (eg, start the receiver to monitor radio frequency based on the entire system bandwidth). It may be applicable to any multicarrier or wideband system (not required). The UE may monitor narrowbands (eg, single carriers for multiple eCCs, anchor carriers, control subbands, etc.) for control messages that include permission to send downlink data. The narrow bandwidth that carries the control message may be part of the system bandwidth or part of the wide bandwidth. The UE can then monitor the bandwidth (eg, all or more carriers of the system bandwidth) for the data according to the control message. Broadband monitoring may include powering additional or alternative circuits, for example, through switching of receiver or transceiver circuits to allow reception over a range of increased frequency spectra. In some examples, a narrowband data transmission or transmission gap may be scheduled between the control message and authorization. This gap may give the UE time to process one or more permits and prepare the UE's receiver circuitry to switch to receiving downlink transmissions over a wide band. In some cases, control messages (including permissions) and data transmissions may be received at the same transmission time interval (TTI). In another example, data transmissions can be received at a TTI according to the permissions received at the previous or previous TTI (eg, cross-transmission opportunity downlink permissions), for example, a clear channel assessment (CCA) fails The data transmission related to authorization takes place in one or more TTIs after the previous TTI. In another example, the UE may not receive or successfully receive a control message indicating permission for the downlink data transmission resource, in which case the UE may enter discontinuous receive (DRX) mode.

Monitoring most or all carriers of the system bandwidth in a system that supports carrier aggregation (eg, broadband systems such as extended component carriers (eCC) or multicarrier systems) can result in excessive power consumption. .. Transmissions directed to the user equipment (UE) may not span the entire system bandwidth or may not be present within a given time period. In one example, a UE may monitor several carriers in the system bandwidth for permissions, even if grants can be scheduled for the UE on a single carrier. For more efficient power utilization, the UE may use a portion of the system bandwidth (eg, a bandwidth that includes several carriers) of the system bandwidth (eg, narrow bandwidth (narrow bandwidth) or anchor carrier). Can be monitored. For example, the UE first receives an instruction that data transmission from a base station spans more than a monitored subset of system bandwidth (eg, monitored narrowband or anchor carrier) (for example,). Can be switched to monitor the entire system bandwidth (using a wideband receiver). In some cases, the UE may use a narrowband receiver to monitor the authorization and then open or activate the wideband receiver circuitry of the UE's receiver according to the information provided by the authorization. For example, a permit may indicate that one or more carriers within the system bandwidth contain data for the UE for part or all of the indicated transmission time interval (TTI). The authorization may indicate a downlink data transmission resource for the UE at the current TTI or a subsequent TTI. In some cases, the base station provides the authorization and downlink data transmission resources to allow the UE to decrypt the authorization and give it processing time to switch the UE receiver circuit from narrowband reception to wideband reception. The gap between the relevant data transmissions can be scheduled. In other cases, the base station is on the same carrier as the grant (eg, on the carrier monitored by the UE) after the grant, but during a time period prior to data transmission across the system bandwidth. Data transmission can be scheduled. Alternatively, the base station may transmit cross-TTI and / or cross-transmission opportunity (TxOP) downlink permissions at the previous TTI so that data transmission occurs at the later TTI and / or later TxOP. ..

Aspects of the present disclosure will first be described in the context of wireless communication systems. Next, an example of a wireless system and a downlink transmission configuration that supports efficient power utilization for eCC will be described. Aspects of the present disclosure are further illustrated and illustrated with reference to equipment diagrams, system diagrams, and flowcharts relating to efficient power utilization for eCC.

FIG. 1 shows an example of a wireless communication system 100 according to various aspects of the present disclosure. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 can be a Long Term Evolution (LTE) / LTE Advanced (LTE-A) network, or a New Radio (NR) network. For example, the wireless communication system 100 may include LTE / LTE-A networks, MuLTEFire networks, neutral host small cell networks, etc. that operate with overlapping coverage areas. The MuLTEFire network may include, for example, an access point (AP) and / or base station 105 communicating in an unlicensed radio frequency spectrum band without an authorized frequency anchor carrier. For example, the MuLTEFire network can operate without anchor carriers in the authorization spectrum. In some cases, the wireless communication system 100 may support extended broadband communication, ultra-reliable (ie, mission-critical) communication, low-latency communication, and communication with low-cost, low-complexity devices. In some examples, the MuLTEfire communication system may support UEs with coverage extended mode. In addition, MuLTEfire communication systems may include and support different UE types. One UE type can be a legacy UE that may lack the ability to cover extended mode. As an addition or alternative, another UE type can be a MuLTEfire UE, which may have the ability for coverage extended mode.

Base station 105 may communicate wirelessly with UE 115 via one or more base station antennas. Each base station 105 may provide communication coverage to its own geographical coverage area 110. The communication link 125 shown in the wireless communication system 100 may include UL transmission from UE 115 to base station 105, or DL transmission from base station 105 to UE 115. The UE 115s may be distributed throughout the wireless communication system 100, and each UE 115 may be fixed or mobile. UE115 is sometimes referred to as mobile station, subscriber station, remote unit, wireless device, access terminal (AT), handset, user agent, client, or similar terminology. UE115 may also be a mobile phone, wireless modem, handheld device, personal computer, tablet, personal electronic device, MTC device, and the like.

The base station 105 may communicate with and communicate with the core network 130. For example, base station 105 may interface with core network 130 via backhaul link 132 (eg, S1). Base stations 105 may communicate with each other directly or indirectly (eg, through core network 130) via backhaul link 134 (eg, X2). Base station 105 may perform radio configuration and scheduling for communication with UE 115, or may operate under the control of a base station controller (not shown). In some examples, base station 105 may be a macro cell, a small cell, a hotspot, and the like. Base station 105 may also be referred to as eNodeB (eNB) 105.

Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, and broadcasting. These systems may be able to support communication with multiple users by sharing available system resources (eg, time, frequency, and power). Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, and orthogonal frequency division multiple access (OFDMA) systems. Is done. A wireless multiple access communication system may include several base stations, each of which simultaneously supports communication for one or more communication devices, which may also be known as a UE.

In some cases, the wireless communication system 100 (eg, a broadband system or a multi-carrier system) may support communication between base station 105 and UE 115 over the system bandwidth using eCC. The system bandwidth may include multiple carriers or subbands (eg, control subbands), each spanning a subset of the system bandwidth. Base station 105 may transmit data to UE 115 through a subset of carriers included in the system bandwidth, for example, depending on the scheduling decision at base station 105. In some cases, wideband data transmission from base station 105 may include data for multiple UE 115. In addition, data transmission from base station 105 to UE 115 may be paired with a downlink permission or control message indicating the allocation of resources for downlink data transmission.

Base station 105 may transmit data over communication link 125 using a subset of carriers within the system bandwidth. Thus, the UE 115 may use, for example, a wideband receiver circuit to monitor system bandwidth for data from base station 105 across one or more carriers. In some cases, base station 105 may simultaneously transmit downlink permissions and data to UE 115. In some examples, base station 105 may transmit downlink permissions using a narrow bandwidth, or a single carrier on a bandwidth narrower than the data transmission bandwidth. In such an example, consistent monitoring of system bandwidth (eg, larger bandwidth) for data transmission using wideband receiver circuitry can be associated with increased or high power consumption. The UE 115, which is still configured to switch to wideband for receiving wideband data transmissions based on the downlink transmit resources specified by the permission, while supporting narrowband monitoring for downlink permission, is quite significant. Can save power.

In some cases, UE 115 or base station 105 may operate in a shared or unlicensed frequency spectrum. These devices can perform a listen before talk (LBT) procedure, such as a clear channel assessment (CCA), prior to communicating to determine if a channel is available. The CCA may include energy detection procedures to determine if there are any other active transmissions that use a particular channel in the shared radio frequency spectrum band. For example, the device can infer that a change in the received signal strength indication (RSSI) of the electricity meter indicates that the channel is occupied. Specifically, signal power that is concentrated in a certain bandwidth and exceeds a predetermined noise floor may indicate another wireless transmitter. The CCA may also include the detection of specific sequences indicating the use of channels. For example, another device may transmit a particular preamble before transmitting a data sequence that indicates that the channel is occupied and may also indicate the time period associated with the transmission of the other device.

In some cases, the wireless communication system 100 may utilize one or more eCCs, for example, single or few eCCs in narrowband and more or more eCCs in wideband. eCC can be characterized by one or more features, including flexible bandwidth, different TTIs, and modified control channel configurations. In some cases, eCC can be associated with carrier aggregation (CA) configurations or dual connectivity configurations (eg, when multiple serving cells have suboptimal backhaul links). eCC may also be configured for use in unlicensed or shared spectra (eg, if two or more operators are licensed to use the same spectrum).

The eCC, characterized by flexible bandwidth, is not capable of monitoring the full bandwidth or by the UE 115 who prefers to use limited bandwidth (for example, to save power). It may contain one or more segments that may be utilized. In some cases, eCC may utilize a different TTI length than other CCs, which may include the use of reduced or variable symbol duration compared to TTIs of other component carriers (CCs). The symbol duration can remain the same in some cases, but each symbol can represent a separate TTI.

In some examples, eCC may support transmissions using different TTI lengths. For example, some CCs may use a uniform 1ms TTI, while some eCCs may use a TTI length such as a single symbol, symbol pair, or slot. In some cases, shorter symbol durations can also be associated with increased subcarrier intervals. Along with reduced TTI length, eCC can take advantage of dynamic Time Division Duplex (TDD) operation (for example, eCC can switch from DL operation to UL operation for short bursts according to dynamic conditions. ). Flexible bandwidth and variable TTI can be associated with modified control channel configurations (for example, eCC can utilize extended physical downlink control channels (ePDCCH) for DL control information). For example, one or more control channels of eCC may utilize frequency division multiplexing (FDM) scheduling to adapt to the use of flexible bandwidth.

In some examples, base station 105 may reserve channels within the shared radio frequency spectrum band through the LBT procedure performed by base station 105 for the duration associated with TxOP. The TxOP may correspond, for example, to the duration of the radio frame, which may include both downlink transmission from base station 105 to UE 115 and uplink transmission from UE 115 to base station 105.

In some cases, the UE 115 may continuously monitor the communication link 125 for instructions that the UE 115 may receive data. In other cases (eg, to save power and extend battery life), the UE 115 may consist of discontinuous receive (DRX) cycles. The DRX cycle can include an "on duration" in which the UE 115 can monitor control information (eg, on the PDCCH), and a "DRX period" in which the UE 115 can power down the radio components. In some cases, the UE 115 may consist of short-term DRX cycles and long-term DRX cycles. In some cases, UE115 may enter a long-term DRX cycle if it is inactive during one or more short-term DRX cycles. The transition between short-term DRX cycles, long-term DRX cycles, and continuous reception can be controlled by an internal timer or by messaging from base station 105. UE115 may receive scheduling messages on the PDCCH during the on duration. The UE 115 may start a "DRX inactivity timer" while monitoring the PDCCH for scheduling messages. If the scheduling message is successfully received, the UE 115 can be ready to receive the data and the DRX inactivity timer can be reset. When the DRX inactivity timer expires without receiving a scheduling message, the UE 115 can move to a short-term DRX cycle and start a "DRX short-term cycle timer". When the DRX short-term cycle timer expires, UE115 may resume the long-term DRX cycle.

The wireless communication system 100 may support a radio resource control (RRC) protocol in which E-UTRAN handles Layer 3 control plane signaling that controls the behavior of the UE. The RRC protocol supports the transfer of common and dedicated non-access layer information. The RRC protocol covers several functional areas including system information (SI) broadcasting, connection control including handover within LTE, network-controlled wireless access technology-to-radio access technology (RAT) mobility, and measurement configuration and reporting. See 3GPP TS36.300 Section 7 and TS36.331.

FIG. 2 shows an example of a wireless communication system 200 for efficient power utilization for eCC. UE115-a may monitor a reduced subset of system bandwidth (eg, anchor carriers or carriers 205-a transmitted in narrow bands) for more efficient power utilization. UE115-a then first receives an instruction that data transmission from base station 105-a spans more than a monitored subset of system bandwidth (eg, carrier 205-a), and then (for example, carrier 205-a). For example, a wideband receiver circuit can be used to switch to monitor the entire system bandwidth (for example, Carrier 205-a and Carrier 205-b). That is, UE115-a may monitor a subset of system bandwidth (eg, carrier 205-a) for downlink allow 210, which may indicate the TTI and radio frequency range associated with data transmission from base station 105-a. .. The anchor carrier (eg, carrier 205-a) can be a given narrowband or a given single carrier within a frame or TTI. In some cases, the anchor carrier can point to a control subband. In some examples, the UE 115-a may power off the wideband receiver circuit and power on the narrowband receiver circuit to monitor the downlink allow 210. In some cases, part of the narrowband receiver circuit may be shared with the wideband receiver circuit and may not be powered down with the rest of the narrowband receiver circuit. However, the circuits associated with wideband monitoring, which can be the majority of the circuits, are powered down when switched to monitor narrowband frequencies by narrowband receiver circuits, thus significantly reducing power consumption.

After processing and decrypting the downlink permission 210, the UE115-a sends the data over a wide band of radio frequencies (for example, through both the carrier 205-a and other carriers including the carrier 205-b). The wideband receiver circuit may be powered up for reception. Correspondingly, base station 105-a prepares the receiver circuit so that UE115-a processes the downlink permission 210, decodes it, and switches from the narrowband receiver circuit to the wideband receiver circuit, and the receiver circuit. You can schedule the time to switch. In the wireless communication system 200, block 215 may represent the time scheduled by base station 105-a for UE 115-a. In some cases, block 215 is for giving UE115-a time to process and decode downlink allow 210 and use the wideband receiver circuit to prepare it to switch on. There can be a time gap between the downlink allow 210 and the data transmission 220 (eg, no downlink transmission). As an addition or alternative, block 215 provides a first set of data in block 215 (eg, using a narrowband receiver circuit that is already powered to monitor and receive downlink permission 210). Represents one or more data transmissions on a narrowband or anchor carrier following downlink allow 210 for UE115-a to process downlink allow 210 and give time to switch receiver circuits while receiving. obtain. In some examples, block 215 may represent the first part of the physical downlink shared channel (PDSCH). In some examples, in block 215, while UE115-a is receiving the first set of data, UE115-a processes, decodes, and / or wideband receiver for downlink permission 210. You may be prepared to switch the circuit on. In yet another example, other data or control signals are received during block 215 while downlink permission 210 is decoded and / or UE115-a prepares to switch its wideband receiver circuit on. obtain. In addition, base station 105-a may transmit a downlink permit 210 at the previous TTI indicating information related to data transmission at the subsequent TTI. In such cases, block 215 may represent the time between the previous TTI and the subsequent TTI.

In some examples, base station 105-a may monitor a single carrier 205-a (eg, anchor carrier or control subband) in a frame or TTI for downlink authorization 210 indicating resource allocation. UE115-a can be configured. In another example, base station 105-a may not configure UE115-a to monitor any carrier. In such a case, UE115-a may enter DRX mode within a frame or TTI and monitor subsequent frames or TTIs on a regular basis. Base station 105-a also monitors different carriers or control subbands for downlink authorization 210 so that different UE 115s may have different anchor carriers that monitor authorization for downlink data transmission resources. Can be configured. For example, a single carrier may not be able to support downlink allowed transmissions for all UE115s in a broadband system. In some cases, UE115-a may first monitor a given carrier or total system bandwidth for control messages that may include anchor carrier instructions for future monitoring of authorization 210 and / or authorization 210. ..

Base station 105-a may schedule a gap 215 between downlink allow 210 and data transmission 220 to give processing time in UE 115-a. In some cases, the gap 215 between the downlink allow 210 transmission and the data transmission 220 may not include communication between base stations 105-a and UE 115-a. The duration of the gap 215 may give the UE 115-a time to process the downlink allow 210 and switch to wideband monitoring (eg, powering additional receiver circuitry). In some cases, the gap 215 may be between the downlink allow 210 and the data transmission 220 in a system using time division multiplexing (TDM). Therefore, the UE 115-a may decide to process the downlink permission 210 and monitor the bandwidth (eg, carriers 205-a and 205-b) for the data transmission 220 based on the downlink permission.

In another example, base station 105-a is on a narrow band (eg, carrier 205-a) monitored by UE115-a between downlink allow 210 and the second part of PDSCH data transmission 220. The first part of PDSCH data 215 may be transmitted. The duration of transmission of the first part of PDSCH data 215 may give UE 115-a time to process the downlink allow 210 and switch to or prepare for broadband monitoring. In some cases, the duration of the first part of PDSCH data transmission 215 may be signaled at downlink authorization 210, signaled in a radio resource control (RRC) configuration, or broadcast to the UE in a broadband system. Base station 105-a indicates the first part of PDSCH data transmission 215 in downlink permission 210, this first data transmission over the narrowband (eg, carrier 205-a) monitored by UE115-a. 215 can be sent. After processing the downlink permission 210, UE115-a states that the subsequent data transmission 220 indicated in the downlink permission 210 may cover a similar narrowband (eg, carrier 205-a) or wideband (eg, carrier 205-a). , Carrier 205-a and Carrier 205-b) (eg, system bandwidth) may be determined to be able to cover all or part of it. A second portion of the PDSCH data transmission 220 can then be received via system bandwidth (eg, via carrier 205-a and carrier 205-b via wideband receiver circuitry).

As an addition or alternative, UE115-a may receive cross-TTI downlink permission 210 or cross-TxOP downlink permission 210 for data transmission 220 contained in subsequent TTIs. Therefore, the time between the pre-TTI and the post-TTI may give UE 115-a time to process the downlink allow 210 and switch to wideband monitoring. For example, base station 105-a may transmit a downlink permission 210 at a first TTI (eg, TTI1) indicating information related to data transmission 220 contained in a later TTI (eg, TTI2). Thus, UE115-a may monitor and receive data in the TxOP based on the downlink permission 210 received in the previous TTI. For example, the permissions received may indicate a set of carriers within the system bandwidth that carry the data transmission.

FIG. 3 shows an example of a downlink transmission configuration 300 for efficient power utilization for eCC. In the example of FIG. 3, base station 105 may schedule a gap between downlink authorization and data transmission to give processing time in UE 115.

In some cases, base station 105 may communicate with UE 115 for a duration of 305. Duration 305 may represent TTI or some other duration (eg, TxOP). For example, the duration 305, which may represent TTI, may start before preamble 315 or end following PDSCH data 330.

In this example, base station 105 has a single carrier (eg, narrow bandwidth or first bandwidth 310-a) or multiple carriers (eg, system bandwidth or a subset of system bandwidth) for at least duration 305. ) Can be used to communicate with the UE 115 over the system bandwidth (eg, first bandwidth 310-a and second bandwidth 310-b).

That is, the base station 105 may transmit data to the UE 115 via the first bandwidth 310-a, which may monitor the first bandwidth 310-a using, for example, a narrowband receiver circuit. .. In addition, base station 105 may transmit data over both the first bandwidth 310-a and the second bandwidth 310-b. In such an example, the UE115 uses, for example, the UE115's receiver or transceiver wideband receiver circuitry to provide system bandwidth (eg, first bandwidth 310-a and second bandwidth 310-b. ) Can be monitored.

The base station 105 may transmit the preamble 315 to the UE 115 to synchronize the transmission timing with the UE 115. In some cases, base station 105 may transmit preamble 315 using narrowband or single carriers (eg, anchor carriers). The UE 115 may, for example, monitor a single carrier using a narrowband receiver circuit, and the UE 115 may receive and decode the preamble 315 and interpret the synchronization information contained in the preamble 315. In some cases, the UE 115 may include a wideband receiver circuit that may be powered off. In some cases, the UE 115 is preconfigured (eg, by base station 105 using RRC signaling or other configuration signaling) to monitor the carrier on which the preamble is received (eg, the anchor carrier). May be good.

Base station 105 may then send downlink permission 320 to UE 115 to indicate the allocation of resources for communication with UE 115 (eg, downlink resources). In some cases, base station 105 may use narrowband or single carrier to transmit downlink allow 320. The UE115 may, for example, monitor a single carrier using a narrowband receiver circuit, which receives the downlink allow 320, decrypts it, and identifies the resource allocation associated with the downlink transmission for the UE115. Can be. Downlink permission 320 may also include resource allocation for other UE 115. In some cases, the resource allocation may indicate a time and frequency resource such as a TTI or part of the TTI associated with subsequent downlink data transmission for UE115, and a range of frequency resources. In some examples, the UE 115 may power off the narrowband receiver and power on the wideband receiver based on the resource allocation indicated in downlink allow 320.

Therefore, base station 105 may give UE 115 time to process and decrypt downlink permission 320. Further, the downlink permission 320 may indicate that the base station 105 may transmit data over multiple carriers or widebands of radio frequencies. In such cases, base station 105 may schedule the time for UE 115 to prepare its receiver to switch from using the narrowband receiver circuit to the wideband receiver circuit. For example, base station 105 prepares a receiver circuit for UE115 to process, decode, and switch downlink permissions, and uses a narrowband receiver circuit to monitor narrowband, thus a wideband receiver circuit. A gap 325 may be scheduled between the downlink allow 320 and the bandwidth data transmission to give time to prepare and / or switch to monitor the bandwidth using. The gap 325 between the downlink allow 320 and the data transmission may be the lack of communication between the base station 105 and the UE 115. In some cases, the duration of the gap 325 may be signaled to UE 115 by base station 105 in the RRC configuration at the beginning of the radio link configuration.

Base station 105 then receives downlink data (eg, PDSCH data 330) over multiple carriers or widebands of radio frequencies (eg, first bandwidth 310-a and second bandwidth 310-b). Can be sent. Gap 325 may provide sufficient time for the UE 115 to process and decode downlink permissions, prepare the receiver circuit for switching from narrowband monitoring to wideband monitoring, and switch the receiver circuit. The UE 115 can then use the wideband receiver circuit to receive PDSCH data 330 over multiple carriers or wide bandwidth. In some examples, multiple carriers may be adjacent to each other. In another example, one or more of the carriers may be separated by carriers that are not covered by the permit (eg, not included in it). In any example, the UE 115 may monitor multiple carriers indicated by authorization via a wideband receiver.

FIG. 4 shows an example of a downlink transmission configuration 400 for efficient power utilization for eCC. In the example of FIG. 4, base station 105 may transmit the first part of PDSCH data over a narrow band monitored by UE 115 between the downlink permission and the second part of PDSCH data.

In some cases, base station 105 may communicate with UE 115 for a duration of 405. Duration 405 may represent TTI or some other duration (eg, TxOP).

Base station 105 uses a single carrier (eg, narrowband or first bandwidth 410-a) or multiple carriers (eg, system bandwidth or subset of system bandwidth) for at least a duration of 405. Can then communicate with the UE 115 via system bandwidth 410 (eg, first bandwidth 310-a and second bandwidth 310-b). That is, the base station 105 may transmit data to the UE 115 via the first bandwidth 410-a, which may monitor the first bandwidth 410-a using, for example, a narrowband receiver circuit. .. In another example, base station 105 may transmit data over the first bandwidth 410-a and the second bandwidth 410-b. In such an example, the UE 115 uses, for example, a wideband receiver circuit to include one or more system bandwidths (eg, first bandwidth 410-a and second bandwidth 410-b). Other bandwidth) can be monitored.

The base station 105 may transmit the preamble 415 to the UE 115 to synchronize the transmission timing with the UE 115. In some cases, base station 105 may transmit preamble 415 using narrowband or single carriers (eg, anchor carriers). The UE 115 may, for example, monitor a single carrier using a narrowband receiver circuit, and the UE 115 may receive and decode the preamble 415 and interpret the synchronization information contained in the preamble 415. In some cases, the UE 115 may include a wideband receiver circuit that may be powered off. In some cases, the UE 115 may be preconfigured to monitor the carrier on which the preamble is received (eg, the anchor carrier).

Base station 105 may then send downlink permission 420 to UE 115 to indicate the allocation of resources for communication with UE 115 (eg, downlink resources). In some cases, base station 105 may transmit downlink allow 420 using narrowband or single carrier. The UE115 may, for example, monitor a single carrier using a narrowband receiver circuit, which may receive and decode the downlink allow 420 to identify resource allocations associated with the downlink transmission. In some cases, the resource allocation may indicate the TTI or part of the TTI associated with subsequent downlink data transmission, and the range of frequency resources. In some examples, the UE 115 may power off the narrowband receiver and power on the wideband receiver based on the resource allocation indicated in downlink allow 420. In another example, some of the narrowband receiver circuitry can be the same as the wideband receiver circuitry and may not be powered down, but additional circuitry is at the wideband bandwidth shown in downlink permission 420. Can be powered to enable reception of.

Thus, base station 105 may schedule time for UE 115 to process and decrypt downlink permission 420. Further, the downlink allow 420 may indicate that the base station 105 may transmit data over multiple carriers or widebands of radio frequencies. In such a case, the base station 105 prepares the receiver circuit to switch the receiver circuit from the narrowband receiver to the wideband receiver, and schedules the time for the UE 115 to switch from the narrowband receiver to the wideband receiver. Or, in some cases, give time. For example, base station 105 allows the UE 115 to process downlink permissions, decode, prepare the receiver circuit for switching, and give time to switch from the narrowband receiver circuit to the wideband receiver circuit. Sends the first PDSCH data portion 425 over a single carrier or narrowband between downlink permission 420 and wideband data transmission (eg, via an anchor carrier for which a control message or permission was received by UE115). obtain. In some cases, the first PDSCH data portion 425 may be associated with a second PDSCH data portion (eg, PDSCH data 430) that base station 105 may transmit over multiple carriers or broadband.

Base station 105 then receives PDSCH data 430 (eg, second PDSCH) via multiple carriers or widebands of radio frequencies (eg, first bandwidth 410-a and second bandwidth 410-b). Data part) can be sent. Transmission of the first PDSCH data portion 425 (eg, on a narrowband or anchor carrier) is (eg, while receiving the first PDSCH data portion 425 through the active narrowband receiver circuit). UE115 may handle downlink permissions, decrypt, prepare the receiver circuit to switch from narrowband monitoring to wideband monitoring, and give enough time to switch the receiver circuit. The UE 115 can then use the wideband receiver circuit to receive PDSCH data 430 over multiple carriers or wide bandwidth. In some cases, the carriers may be adjacent to each other, and in other cases, the carriers may be separated by carriers not indicated by their permission. In either case, the UE 115 may monitor multiple carriers indicated by authorization via a wideband receiver. In some cases, the first bandwidth 410-a may overlap with the second bandwidth 410-b. Further, the first bandwidth 410-a may be part of the second bandwidth 410-b (eg, as shown). Alternatively, the first bandwidth 410-a and the second bandwidth 410-b may not overlap in other scenarios.

FIG. 5 shows an example of a downlink transmission configuration 501 for efficient power utilization for eCC and a receiver circuit power consumption graph 502. In the example of Figure 5, the UE may receive cross-TTI downlink or cross-TxOP downlink permissions for data transmissions contained in subsequent TTIs.

In some cases, the downlink transmission configuration 501 may represent the point of view of base station 105. Base station 105 has a narrow band of radio frequencies (eg, single carrier or first bandwidth 510-a) or a wide band of radio frequencies (eg, for example) over a duration (eg, durations 505-a to 505-d). Downloading permissions and data may be sent to multiple UE 115s via multiple carriers or both the first bandwidth 510-a and the second bandwidth 510-b). In some examples, the durations 505-b to 505-d may represent individual TTIs, parts of TTIs, or some other duration, respectively. Duration 505-a may represent the duration prior to the receipt of permission 515-a and execution of CCA520, but may not necessarily correspond to the same duration as durations 515-b to 515-d. ..

In some examples, base station 105 transmits permission 515 and / or data to UE 115 over a first bandwidth 510-a, where UE 115 uses, for example, a narrowband receiver circuit. Bandwidth 510-a can be monitored. In another example, base station 105 may transmit data and / or authorization to UE 115 via both the first bandwidth 510-a and the second bandwidth 510-b (eg, wideband). In such an example, the UE 115 uses, for example, a wideband receiver circuit to include one or more system bandwidths (eg, first bandwidth 510-a and second bandwidth 510-b). Other bandwidth) can be monitored.

Base station 105 may transmit downlink permission 515 to multiple UEs 115 in the wireless communication system to indicate the allocation of resources for communication with each UE. In some cases, base station 105 may transmit downlink permission 515 using narrowband or single carrier (eg, first bandwidth 510-a). The UE115 may, for example, use a narrowband receiver circuit to monitor the first bandwidth 510-a, which receives the downlink permission 515, decodes it, and is associated with subsequent downlink transmissions. Can identify the resource allocation to be done. Downlink permissions 515-b to 515-d may indicate resource allocations associated with data transmission in subsequent durations. For example, downlink permission 515-b may indicate a resource allocation associated with data transmission at duration 505-c. In some examples, base station 105 may or may not come immediately before the associated data transmission (eg, data transmission via UE4 resource 530 or other UE resource 525) previous duration 505- Downlink permission 515-a may be sent at a.

In such cases, base station 105 may run CCA520 on the channel used to communicate with UE 115. In case of CCA failure, the base station may defer data transmission to UE115. If base station 105 determines that the CCA (eg, CCA520) has passed, base station 105 may transmit data to UE 115 over the channel. The UE 115 may then use the resources indicated in downlink permission 515 to receive data transmissions from base station 105. That is, the downlink permission 515 can be applied to subsequent downlink transmissions regardless of the time the data transmission is received by the UE 115. That is, authorization 515-a may indicate the allocation of downlink resources for transmissions that are not received by the intended UE 115 until the CCA520 procedure is successful. If the CCA520 fails, the downlink transmission associated with permission 515-a may be received at a duration of 515 following a successful subsequent CCA520.

In some cases, downlink authorization 515 may indicate resource allocation for multiple UEs in a broadband system (eg, other UE resources 525 indicating resources for any UE1, UE2, UE3, and UE5). In some cases, downlink authorization 515 may allocate resources for a subset of multiple UEs. For example, downlink authorization 515-b allocates resources for UE1, UE2, UE3, UE4, and UE5, while downlink authorization 515-c allocates resources for UE1, UE2, UE3, and UE5. Can be assigned. The UE 115 may receive and decrypt the downlink permission 515 to determine whether the base station 105 will send data to the UE 115 in subsequent TTIs. In addition, the UE 115 may determine whether the downlink allowance 515 indicates data transmission over narrow or wide bandwidth. Based on this decision, the UE 115 may power off the narrowband receiver circuit and power on the wideband receiver circuit in order to receive data over wideband radio frequencies. In some cases, some of the narrowband receiver circuitry can be the same as the wideband receiver circuitry and may not be powered down, but additional circuitry allows for wideband reception of frequencies. Can be powered to do so.

In some cases, the receiver circuit power consumption graph 502 may represent a point of view of the receiver power consumption of UE115 (eg, UE4). UE4 powers on the narrowband receiver circuit and powers off additional circuits associated with wideband monitoring simply to monitor the downlink permission 515 from base station 105 in the narrowband or anchor carrier. obtain. The power block 535 may represent the amount of power used by the UE 115 to receive the downlink transmission. For example, base station 105 sends downlink permission 515-b, UE115 receives downlink permission, and the amount of power indicated in power block 535-a (eg, power associated with narrowband monitoring). Can be used. UE115 may process and decrypt downlink permission 515-b and determine that the base station can transmit data for a subsequent duration of 505-c. The UE 115 may then power additional wideband receiver circuitry (eg, power associated with wideband monitoring) to receive data transmissions (eg, power block 535-b). In some examples, the UE 115 may receive the data transmission and use the amount of power shown in power block 535-b. Data transmission may be paired with downlink permission 515-c from base station 105. UE115 may process and decrypt downlink permission 515-c and determine that the base station may not transmit data directed to it (eg, UE4) for a subsequent duration of 505-d. Therefore, UE4 may power off the wideband receiver circuit and power on the narrowband receiver circuit to monitor subsequent downlink permissions 515-d.

When monitoring using a narrowband receiver circuit, the UE115 may receive downlink permissions over a portion of duration 505-b (for example, from the start of duration 505-b to cutoff time 540). .. This portion of duration 505-b may be shorter than the time required to receive a data transmission. For example, the UE 115 may receive data transmissions over the duration 505-c, while the UE 115 may receive downlink permissions over a portion of the duration 505-b indicated by the cutoff time 540. The reduction in receive time associated with authorized transmission when using the narrowband receiver circuit is powered for power block 535-a where the narrowband receiver circuit does not span the entire duration block 505-b. Therefore, the power consumption in UE4 can be further reduced.

The wireless device 605 may be an example of an embodiment of UE 115 as described with reference to FIG.

In some cases, all or some of the circuits of wideband circuit 630 and narrowband circuit 625 may be the same or shared. In other cases, the wideband circuit 630 and narrowband circuit 625 may be part of separate components (eg, two separate receivers 610).

The downlink manager 615 monitors the first bandwidth by the receiver of the wireless device, and in the first bandwidth, it may receive a control message including the permission of the downlink data transmission resource for the wireless device. The downlink manager 615 then sets the second bandwidth for data transmission on the wireless device as specified by the authorization (for example, if the first bandwidth is part of the second bandwidth). It may be possible to monitor and decide to monitor the second bandwidth by the receiver for data transmission during TTI. For example, the downlink manager 615 may power additional circuitry (eg, broadband circuit 630) of receiver 610 via link 635.

Transmitter 620 may transmit signals generated by other components of the device (eg, transmission information received over link 640). In some examples, the transmitter 620 may be collated with the receiver 610 in the transceiver module. For example, transmitter 620 may be an example of an embodiment of transceiver 935 described with reference to FIG. The transmitter 620 may include a single antenna or may include a set of antennas.

In some cases, the first bandwidth includes a wide band narrow band portion. In some cases, the first bandwidth includes anchor carriers. In some examples, the narrowband monitor 725 may use the narrowband circuit 625-a to perform the functions described. In some cases, the narrowband monitor 725 may receive information from the narrowband circuit 625-a of receiver 710 via link 635-a.

The control message manager 730 may then receive such information from the narrowband monitor via link 745. The information may include control messages including authorization of downlink data transmission resources for wireless devices. In some cases, the control message includes the authorization of the downlink data transmission resource of the second TTI, which follows the TTI monitored by the narrowband monitor 725.

The authorization processor 735 may receive information (eg, authorization) from the control message manager 730 over link 750. Based on this information, the authorization processor 735 may decide to monitor the second bandwidth for data transmission of the wireless device as specified by the authorization. The first bandwidth may be part of the second bandwidth.

Broadband monitor 740 may monitor a second bandwidth with a receiver for data transmission during TTI. In some cases, monitoring the second bandwidth involves monitoring the second bandwidth by the wideband circuit 630-a of receiver 710. In some cases, the second bandwidth includes a wide band. Broadband monitor 740 may receive data transmissions in the second bandwidth during TTI (eg, from receiver 710 via link 635-a), and the authorization associated with data transmission was previously provided by authorization processor 735. Received at TTI. For example, the authorized processor 735 notifies the receiver 710 (eg, via link 635-a) that the broadband monitor 740 monitors data transmissions in accordance with the information (using, eg, broadband circuit 630-a). Information (eg, downlink resource information) can be sent to the broadband monitor 740 over link 755.

FIG. 8 shows FIG. 800 of the downlink manager 815 that supports efficient power utilization for eCC in various aspects of the disclosure. The downlink manager 815 can be an example of aspects of the wireless device 605, wireless device 705, and UE 115 described with reference to FIGS. 1, 6 and 7. The downlink manager 815 may be an example of aspects of the downlink manager 615, the downlink manager 715, or the downlink manager 915 described with reference to FIGS. 6, 7, and 9.

Each of these components may communicate with each other (eg, via one or more buses).

The downlink manager 815 receives information from other components of the wireless device (eg, from the receiver) via link 635-b and to other components of the wireless device via link 640-b (eg, from the receiver). , Can pass information (to the transmitter). The information may be received by, for example, the narrowband monitor 825 and / or the wideband monitor 840 (eg, via link 635-b), depending on the information received and the circuitry used by the receiver. For example, the narrowband monitor 825 may monitor the first bandwidth by the receiver of the wireless device (eg, the narrowband receiver circuit of the receiver via link 635-a). In some cases, the first bandwidth includes a wide band narrow band portion. In some cases, the first bandwidth includes anchor carriers. The wideband monitor 840 may monitor a second bandwidth by a receiver (eg, the wideband receiver circuit of the receiver via link 635-a) for data transmission during TTI. In some cases, the second bandwidth includes a wide band. In some cases, the second bandwidth includes one or more carriers. In some cases, one or more carriers include anchor carriers and one or more other carriers.

As an example, a wireless device may monitor a first bandwidth (eg, by a receiver) for a control message.
